An East Side, West Side Story: Ozone Pollution in the United States

In a new study, academic and NOAA scientists found that ozone pollution is declining at rural sites in the East, but is steady or even increasing at most sites in the rural West, with strongest increases in spring.

Asian emissions can increase ground-level ozone pollution in U.S. West

Springtime air pollution from Asia, swept across the Pacific Ocean on winds, can contribute to episodes of high surface ozone pollution in the western United States.

Monitoring Particles in the Air

As a physical scientist and station chief for the NOAA Earth System Research Laboratory's Mauna Loa Observatory in Hawaii, John Barnes' specialty is lidar (light detection and ranging), often referred to as laser radar, which he uses to identify and measure particles in the atmosphere.

Black carbon larger cause of climate change than previously assessed

Soot, known as black carbon to scientists, is the second largest man-made contributor to global warming, and its influence on climate has been greatly underestimated.

Chemical measurements confirm official estimate of Gulf oil spill rate

New NOAA-led analysis shows gases and oil in three chemically different mixtures deep underwater, in the surface slick, in the air

By combining detailed chemical measurements in the deep ocean, in the oil slick, and in the air, NOAA scientists and academic colleagues have independently estimated how fast gases and oil were leaking during the 2010 Deepwater Horizon oil spill in the Gulf of Mexico.
